Mix together all the ingredients except the chicken in a shallow dish and mix until well combined
Make 3 deep diagonal cuts in each chicken thigh and place into the marinade, turn well to coat all over. Leave in the fridge for 2 hours or overnight is best.

Heat the oven to 200 degrees and place the chicken in a lightly oiled roasting tin, skin side down and roast until juices run clear about 35-40 mins.
